Be it known that I, ARCHIBALD HYDE' Fig. 3. EHLE, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Motor- Driven Trucks, of which the following is a specification.

My-invention relates to that class of trucks in which the drivin mechanism, including the motor, is carriedy the truck.

My invention is particularly' adapted for internal-combusti on l engines, such as gas-engines. l The object offrny invention is to so con'- struct the truck that it will properly support the entire driving mechanism without undue crowding, making the engine suiiiciently large. to properly'propel the car, and yet not increase the rigid wheel-base beyond the ordinary lenffth, so'. that the car will readily pass around the standard curves...

My invention also'relates, further, to departicularly adapted vidual car, using my im roved motor-driven l truck in place vof the or inary;.forward truck' l of the caribut it will be further understood l thatv the invention can be usedsimply as a l locomotive, coupled. Y y l D D are two-'longitudinalfbeamsextendthe manner czlearly illustrated in' Fig: 2. These two beams DD snpport'the engine E, which in the present instance inder gasolene-gas engine the four cylinders being-indicated by. e, and the crank-shaft is contained in the casing e The crank-shaft E projects atv each end 'coupled to the transmitting mechanism in the manner hereinafter described'.-V w l p The engine can be of any ordinary t gas or gasolenev engine; but Ipreferab use gasolene or alcohol. I have simply s own the valves and other`mechanism of the` asengine inv outline, as they .form no part .o ther present invention. I so a verylarge gas-engine, can

Fig. 9 is a sectional view on the line 9 9, Fig. 8, and Fig. 10 is a side .view of a-car mounted on my improved truck. Ay isthe frame of the truck having pedestals a, in which are mounted the boxes a for the axles B B On these axles are the wheels ,t b', respectively. The axle Bis the driving-axle,y which is geared to the motor in the manner fully described hereafter. In l some instances', however,- the axle B may also be drivon'by a` chain or other connection l from the main axle B.

A is a cross-frame carrying the center bearing-platefe, on which lthe car-body is anism being carried'byA a trailin between the main axles for lthe accommodation of an engine yof a's'ufiicie'nt sizetof properly propel the car. In the present instance the cross-frame A-, carrying the center bearing-plate, extends over the engine E so that, as shown in the drawings, the engine is mounted between the two axles and below the crees-frame. While an ordinary size of engine will readily drive a car after it is set in motion, itis very diiiicult, especially on upgrades, to .start a car with a gas-engine. Therefore `a very large gasfenginehas tothe service..

G v is a dynamo, the armature-shaft g of which forms a continuation of the shaft E This dynamo is mounted on the frames D D, as-clearly illustrated in Fig. 1. The shaft g is shapqcd at the end to vreceive a crank, so that t e shaft and theengine-shaft can be pivoted, as clearly shown by dotted linesip It will be understood that my invention for driving anv indi-f of the -casingand 1s design :the truck that 60.: to which atrain'bf carscan be ing the full length of the frameA and bent in ,6.5

is a lfour-cylcofA 8o tween the two axles,"the transmitting mech- .ll'uki E 1 This enables me to use all the ava' able space used in order to 'make'it availablefor' car turned when it is desired to start the engine.

IOO

In some instances the generator may be used as a motor to turn'the crank-shaft of the engine if the electricity is 'stored' in a storage battery. By providing the dynamo G, as

indicated, the lightn and heating ofthe car can be accomplishe without the use of a separate engine. l

In order thatthe forward axle B can be readily removed from theframe, I-make a short connecting-shaft e2, which is coupled to the engine-shaft E and to the dynamo-shaft g, as clearly ,indicated in Figs. 1 and 3. By

' removing this section e2 the axle Bl can be dropped from the frame and readily removed detached from the frame in a similar manner .to the shaftB previously described. The joint e4 is a gimbal-joint, asthere may be a slight variation in the alinement between the two shafts E and I. IThe shaft I2 of the magnetic clutch is connected to the shaft H A the joint et" It will be seen that t understood that `used whether it is a magnetic or mechanical by a gim'b'al-joint i for the same .urpose as oughout the length of thetruckthe shaft is divided into sectionss the several 'sections being united by gimbal-joints, so that each part can have a slightnindependent movement without binding upon the bearings or without 'producing undue friction.

I have shown simply one form of magnetic clutchthat is, the disk type-,but it willbe any form of clutch may be clutch. I prefer to use the magnetic clutch electrically operated, as thev wires can be readily run from the clutch-case to the cab of the, car. By using the clutch the engineshaft can be readily disconnected from the transmission-ge ar'. The transmission-gearing illustrated in the drawings is fully described and claimed in detail in a companion application filed even date herewith. Therefore I will not describe it minutely in this specification. Y

m is the first intermediate shaft, and n is the second intermediate shaft. Loose on the shaft m are gears fm', which mesh with a pinion h on the shaft H. A clutch m2, mounted on the squared portion of the shaftm, is arranged to be shifted by the shifting-s indle 71,2, having a forked arm engaging the c utchsleeve, so that the clutch may be thrown either to the right or left to reverse the move- -wheels N and B2', section e3 directly under the shaft B, so that on 'removing this section the shaft B lcan be` ceases ment of the shaftm or remain in the central positihn clear of the gear-wheels when4 it is desired to disconnect the engine.

Keyed to the shaft lmy are two gear-wheels p p, the Wheel p being less in diameter than the wheel p, and these Wheels gear,respectively, with'wheels q q loose on the shaft n. A clutch-sleeve n is arranged to slide on the squared portion of the shaft to engage either one of the wheels g q, and this clutch-sleeve is shifted by me ans of the spindle h3,.having a forked end', as indicated in Fig, 9, so that when the wheel q the car will be and if thesleeve n is wheel q the car will be driven at low speed. The shaft n extends beyond the frame H? of the speed-box H at each side inthe present driven athigh speed,

instance and is tapered to fit the tapered opening in the sprocket-wheels N N, which are keyed to the shaft, as indicated in Fig. 7. On the aXle B are two sprocket-wheels B2, and drive-chains N pass around the sprocketso that the power is transmitted to theaxles B by the iieXible chain' gearing.

The spindles h2 and h3 are held in their central position by springs h4, Figs. 1 and S. These springs are connected to the levers 71,5,

clutch-sleeve n is in gear with the clutched to the gearand the levers are connected to the rods I of hfdraulic 'cylinders c, the valve Amechanism o which is controlled by electric mechanism similar to that described inmy application` for patent filed September 12, 1905, under Serial No. 278,127. The wires lead from this controlling mechanism to a point on the car TOO within easy access of the driver, so that the v driving mechanism is controlledl entirely vthrough the medium of the electric mechanism.

There ,is preferably no connection between. the carand the truck with the exception of the pivot-pin of the truck and the wire leading from the controller on the car-body to the mechanism on the truck. The position of the truck in respect to the car is clearly indicated in the side view, Fig. 10, which illustrates one form of car onto which my improved truck can be mounted.A The speedbox and transmission-gear,it will be noted', are beyond 1 e' main frame ofthe truck, and

in order to properly` support these I mount a swing-truck F at the rear of the main truck and pivot the swing-truck sionl of the base-frame H2, as clearly illustratedin Figs. 1, 3, and 9. The truck F is framed to support the boxes s of the shaft S,

on which are mounted the wheels s, and exat f to an extentending imm the-frame of the. truck is a curved radius member'F, which travels in a suitable support on the forward portion of the Vspeed-boit framev H2. The framej", to which the efxtension of the speed-box frame H2 is pivote`d, is connected by links]02 to the proper working of the main truck;

' enabled to mount the-axles B B in a manner 1o I can utilize an eqnalizin-beam. u, which A swin -truck F supportsthe rear end' ofthe main frame f 3, carrying the boxes,A so that the axle .is free to swing independently of the main 'truck and will 'take the curves-'ind'enel1dentlyv of the main truck, so that While the' Spee -bX it does not interfere` withv the f By'the construction above describedl am similar to the axles of an ordinary truck, and

This will. relievel the engine and other parts lof the mechanism from'severe shocks and make the truck'ride more evenly than if the axles were mounted boxes on the trucltalne. y
